Changes in contraceptive and sexual behaviours among unmarried young people in Nigeria: Evidence from nationally representative surveys.

CONTEXT

Nigeria is a high-burden country in terms of young people's health. Understanding changes in young people's sexual and reproductive health (SRH) behaviours and the associated factors is important for framing appropriate interventions.

OBJECTIVE

This study assessed changes in SRH behaviours of unmarried young people aged 15-24 and associated factors over a ten-year period in Nigeria.

DATA AND METHOD

We analysed datasets from Nigeria Demographic and Health Surveys of 2008, 2013 and 2018 to assess changes in inconsistent condom use, non-use of modern contraceptives; multiple sexual partnership; and early sexual debut. Using binary logistic regression, we assessed the association of selected variables with the SRH behaviours.

RESULTS

Over four-fifths of unmarried young people (15-24) in Nigeria engaged in at least one risky sexual behaviour in each survey year. The pattern of changes in the four risky SRH behaviours was consistent over the 10-year period, with the highest rates of each behaviour occurring in 2018 while the lowest rates were in 2013, thus indicating an increase in the proportion of respondents engaging in risky sexual behaviours over the study period. Comprehensive HIV/AIDS knowledge, male gender, older age category (20-24), residence in south-west Nigeria, urban residence, higher socio-economic status, secondary/higher education were mostly protective against the four SRH variables analysed across the different data waves.

CONCLUSION

Addressing the high and increasing level of risky SRH behaviours among young people in Nigeria is imperative to improve overall national health status and to ensure progress towards achieving SDG target 3.7 focusing on SRH.
